# Building Slic3r PE on Mac OS
|
||
|
|
|
||
|
|
To build Slic3r PE on Mac OS, you will need to install XCode and an appropriate SDK.
|
||
|
|
You will also need [CMake](https://cmake.org/) installed (available on Brew) and possibly git.
|
||
|
|
|
||
|
|
Currently Slic3r PE is built against the Mac OS X SDK version 10.9.
|
||
|
|
Building against older SDKs is unsupported. Building against newer SDKs might work,
|
||
|
|
but there may be subtle issues, such as dark mode not working very well on Mojave or other GUI problems.
|
||
|
|
|
||
|
|
You can obtain the SDK 10.9 for example [in this repository](https://github.com/phracker/MacOSX-SDKs).
|
||
|
|
If you don't already have the 10.9 version as part of your Mac OS installation, please download it
|
||
|
|
and place it into a reachable location.
|
||
|
|
|
||
|
|
The default location for Mac OS SDKs is:
|
||
|
|
|
||
|
|
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
|
||
|
|
|
||
|
|
Wherever the 10.9 SDK is, please note down its location, it will be required to build Slic3r.
|
||
|
|
|
||
|
|
On my system, for example, the path to the SDK is
|
||
|
|
|
||
|
|
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
|
||
|
|
|
||
|
|
### Dependencies
|
||
|
|
|
||
|
|
Slic3r comes with a set of CMake scripts to build its dependencies, it lives in the `deps` directory.
|
||
|
|
Open a terminal window and navigate to Slic3r sources directory and then to `deps`.
|
||
|
|
Use the following commands to build the dependencies:
|
||
|
|
|
||
|
|
mkdir build
|
||
|
|
cd build
|
||
|
|
cmake .. -DDEPS_OSX_SYSROOT=<path to the 10.9 SDK>
|
||
|
|
|
||
|
|
This will create a dependencies bundle inside the `build/destdir` directory.
|
||
|
|
You can also customize the bundle output path using the `-DDESTDIR=<some path>` option passed to `cmake`.
|
||
|
|
|
||
|
|
### Building Slic3r
|
||
|
|
|
||
|
|
If dependencies built without an error, you can proceed to build Slic3r itself.
|
||
|
|
Go back to top level Slic3r sources directory and use these commands:
|
||
|
|
|
||
|
|
mkdir build
|
||
|
|
cd build
|
||
|
|
cmake .. -DCMAKE_PREFIX_PATH="$PWD/../deps/build/destdir/usr/local" -DCMAKE_OSX_SYSROOT=<path to the 10.9 SDK>
|
||
|
|
|
||
|
|
The `CMAKE_PREFIX_PATH` is the path to the dependencies bundle but with `/usr/local` appended - if you set a custom path
|
||
|
|
using the `DESTDIR` option, you will need to change this accordingly. **Warning:** the `CMAKE_PREFIX_PATH` needs to be an absolute path.
|
||
|
|
|
||
|
|
The CMake command above prepares Slic3r for building from the command line.
|
||
|
|
To start the build, use
|
||
|
|
|
||
|
|
make -jN
|
||
|
|
|
||
|
|
where `N` is the number of CPU cores, so, for example `make -j4` for a 4-core machine.
|
||
|
|
|
||
|
|
Alternatively, if you would like to use XCode GUI, modify the `cmake` command to include the `-GXcode` option:
|
||
|
|
|
||
|
|
cmake .. -GXcode -DCMAKE_PREFIX_PATH="$PWD/../deps/build/destdir/usr/local" -DCMAKE_OSX_SYSROOT=<path to the 10.9 SDK>
|
||
|
|
|
||
|
|
and then open the `Slic3r.xcodeproj` file.
|
||
|
|
This should open up XCode where you can perform build using the GUI or perform other tasks.
